Basically it's what if Captain America was a DC hero rather than a Marvel Hero? What if the Justice League found him after the 'The Enemy Below' episode where the incident caused the ice to shift causing one of the League members to find him.
When he first wakes up he attacks the League thinking that he's still in the 40's and they're a part of Hydra.
His main enemies will be Hydra, Red Skull, Zemo, Arnim Zolo, Baron Von Strucker, King Cobra and the Serpent Society, M.O.D.O.K, Nefarius, Sin, Taskmaster and Winter Soldier.
Main Pairing: Wonder Woman, not immediate but gradual.
I really hope that someone takes this story.
